Google’s latest ad format came out of beta testing yesterday and is being rolled out across the US. Enter, Google Product Listing Ads.

Google Product Listing Ads essentially make AdWords listings more visual by allowing advertisers to list their products with accompanying images.

For an overview of the new feature, watch the video below:

Google explained the benefits of this service on their blog, yesterday, “With Product Ads, users can see the exact products you offer before they even reach your site, which leads to more clicks, higher quality leads, and higher ROI for your search ads.”

During the beta testing stage, Google has seen advertisers list hundreds of millions of products through Product Listing Ads and the findings have been quite remarkable. Google found that people are twice as likely to click on a Product Listing Ad as they are to click on a standard text ad in the same location.

Much like Google Product Extensions, which allows you to add pictures and prices to keyword-targeted text ads, Product Listing Ads makes it easy to present potential customers with the most relevant products from your Google Merchant Center account.

Once Product Listing Ads reach the whole of Google’s advertising database, we can expect to see a great deal more graphical ads. Based on the testing, the service could also mean better returns for advertisers and of course, more revenue for Google.
